THE CLASSICAL PERIOD (1775-1825). The Baroque period culminated in the masterpieces of J.S. Bach and G.F. Handel. In the middle of the eighteenth century, contemporaneous with the mature years of Bach and Handel, a new musical style developed that is known as Rococo or preclassical style.he music of the Classical era is characterized by objectivity. While emotion is an important aspect of all music, in the Classical period, emotions were carefully controlled. This control is evident in the use of dynamics and expressive differences within sections or movements of a composition.
The same thing happens to a rock when it is heated enough. Of course, it takes a lot of heat to melt a rock. The high temperatures required are generally found only deep within the earth. The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper.
The inside of the Earth is very hot - hot enough to melt rocks. Molten (liquid) rock forms when rocks melt. The molten rock is called magma. When the magma cools and solidifies, a type of rock called igneous rock forms. What are they like? Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified. The more slowly the magma cools, the bigger the crystals. You may have done an experiment at school with a substance called salol. If molten salol cools slowly, you get big crystals. If it cools quickly, you get small crystals. Obsidian and basalt. If the magma cools quickly, small crystals form in the rock. This can happen if the magma erupts from a ...
